RING-SPINNING APPARATUS.

SPECIFICATION formingpart of Letters Patent No. 752,238, dated February 16, 1904.

Application filed October 26, 1903.

To all whom it may concern.-

Be it known that I, ALFRED LOVEJOY, a citizen of the United States, and a resident of Lowell, county of Middlesex, State of Massachusetts, have invented an Improvement in Ring-Spinning Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to ring spinning frames and similar apparatus; and it has for its particular object the production of novel means for connecting the ring to the ring-rail in a yielding manner, whereby under intermittent or varying pull of the yarn or for any reason due to variation in speed, draft, &c., the ring may slightly yield and accommodate itself thereto.

Figure 1 is a front elevation of a portion of the ring-rail of a spinning-frame or the like with one embodiment of my present invention applied thereto, a portion of a spindle and bobbin being shown. Fig. 2 is a plan View of the ring and the means for'connecting it in a yielding manner with the ring-rail; and Fig. 3 is a transverse sectional detail of the ring and its holding means, taken on the line 3 3, Fig. 2.

The ring-rail R of a spinning, twisting, or other similar frame having openings, as R, Fig. 2, for the spindle S and bobbin B, Fig.

'1, and the ring (1,, having upper and lower flanges a M, the former constituting a raceway for the traveler 6, may be and are all of usual construction. In the present embodiment of my invention the ring is connected with an annular plate 6, by means of clips or ears 5 thereon, under which the lower flange a is snapped. A second annular plate 0 has an upturned annular web 0 and peripheral notches 0 to receive the shanks of screws 5, by which said plate is firmly secured to the ring-rail concentric with the spindle-opening R. The diameter of the web is such that the plate 6 when superposed thereon will project laterally beyond it, as shown in Figs. 1 and 3,- the members or plates 6 and 0 being connected Serial Nol'78,532. (No model.)

by a loosely-coiled spiral spring .9 surrounding the web 0 and permanently secured at its opposite ends to said plates by solder or in any other suitable manner. The expansibility of the spring normally lifts the plate 6 slightly above the top of the web, as shown inFig. 3, and serves as an elastic cushion to yieldingly support the ring a, while restraining the ring from rotation. Should variations in speed or draft cause intermittent pulls on the yarn, the spring will give or yield slightly thereunder to permit the ring to accommodate itself to the strain, some slight tipping movement of the ring being thereby permitted. Any improper movement of the ring on its cushion or support is limited by the web a, which at such time acts upon the under face of the annular plate Z2, and the web also prevents any movement laterally which would tend to throw the ring out of its concentric relation with the spindle. The connection between the ring and the rail is thus sufiicient to properly restrain the ring from rotation, while sustaining it in a yielding or cushioned manner.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A non-rotatable spinning-ring, a holder therefor, and a spiral spring connecting said ring and holder, preventing rotation of the ring and also yieldingly supporting it.

2. A ring-holder having an upturned annular web, a spring surrounding said web and secured at one end, and a spinning-ring connected with the other end of and yieldingly supported by the spring.

3. A spinning-ring, holding means therefor comprising two annular members one of which is adapted to be fixedly connected to the ring and the other to the ringrail, and an elastic connection between and permanently attached to said members.

4:. A non-rotatable spinning-ring, an annular member adapted to be secured to the ringrail, and a spiral spring permanently attached at one end to the said annular member and at its other end connected with the ring to prevent rotation thereof.

Corrections in Letters Patent 752,238-

5. A spinning-ring, an annular plate detachably connected with the base thereof, a second annular plate adapted to be attached to the ring-rail and having an upturned an- 5 nular web, and a spring coiled around said web, and permanently secured at its ends to the two annular plates.

6. An annular plate adapted to be attached to the ring-rail and having an upturned annular web, a spring coiled about said web and secured at its lower end to the plate, a second annular plate overhanging the web and per manently secured to the upper end of the spring, engaging devices on said second plate,

It is hereby certified that in Letters Patent N 0. 752,238, granted February 16, 1904,

upon the application of Alfred Lovejoy, of Lowell, Massachusetts, for an improvement in Ring-Spinning Apparatus, errors appear in the printed specification requiring correction, as follows: On page 2, line 17, the compound word non-rotatable before the word spinning-frame should be stricken out and inserted before the word spinningring, line 18; and that the said Letters Patent should he read with these corrections therein that the same may conform to the record of the case in the Patent Ofiice.
